While Christian Byzantium survived in the eastern Mediterranean,
the Christian Visigothic kingdom in what are now Spain and Portugal fell to Arab-led Berber armies with remarkable speed in the early 8th century.
This relief carving illustrates the Biblical story of Daniel in the Lion’s Den and, although it is sometimes said to date from a century before the Islamic conquest,
the four soldiers in the lower register look remarkably like early Islamic or Umayyad troops. (Museo Arqueologico, Madrid)
